Peter O'Brien

Where will OíBrien play? Thatís the long-term question surrounding the slugging prospect, who made his MLB debut with Arizona last season though he only recorded 12 plate appearances in eight games. O...

The 24-year-old catching prospect was shipped to Arizona from the Yankees as the main returning piece in the Martin Prado trade. In 2014, he burst on the national prospect scene by belting 34 home runs in 427 plate appearances between High-A and Double-A. Catchers with 30-plus homer pop donít typically show up in the big leagues, and OíBrien probably wonít be the guy to buck that trend. A .351 BABIP allowed him to hit .321 in 30 games at High-A, but upon his promotion to Double-A Trenton, he hit .245 in 72 games before getting traded. He also might not be able to stick behind the plate, as the Yankees had been trying him at first base before the trade, and would presumably have stuck with him at catcher if they thought he could handle it. He should reach Triple-A in short order, but itís unlikely that he will hit enough for his power to continue to play up as he moves up the organizational ladder.
